This board has experimental support in mbed OS, currently under review by the ARM mbed team.


Nuvoton' NUC472 ARM Cortex-M4 based 32-bit microcontrollers.The NuMicro NUC472 Advanced series with embedded Cortex®-M4F core with DSP extensions and a Floating Point Unit runs up to 84 MHz with 256/512 Kbytes embedded flash memories and 64K-byte embedded SRAM. It is also equipped with plenty of peripheral devices, such as Timers, Watchdog Timers, RTC, PDMA, EBI, UART, Smart Card interface, SD HOST, SPI, I2C, I2S, PWM, Timer, GPIO, LIN, CAN, PS/2, 12-bit ADC, analog comparator, operational amplifier, temperature sensor, Low Voltage Reset Controller and Brown-out Detector. The NUC472 also provides Ethernet 10/100 MAC with MII and RMII interface, USB 2.0 full-speed Device/Host/OTG, USB 2.0 HS device and security functions such as tamper detection, symmetric cryptographic accelerator and secure Hash function accelerator.

The Nu-mbed NUC472 has been designed by NuvoTon in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M4®. It is packaged as a development board with connectors to break out to strip board and breadboard.
